Owen Anderson 0c550df9d2 Fix the build. 
llvm-svn: 37705
 2007-06-22 16:59:54 +00:00
Dan Gohman 309d3d51b3 Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from 
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.

Dan Gohman a7644dd9b9 Pass a SelectionDAG into SDNode::dump everywhere it's used, in prepration 
for needing the DAG node to print pre-legalize extended value types, and
to get better debug messages with target-specific nodes.

Chris Lattner 7936d91f70 describe an argument, hide it.

Dan Gohman 9e82064924 Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad 
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.

Evan Cheng a7ca624028 Replace TargetInstrInfo::CanBeDuplicated() with a M_NOT_DUPLICABLE bit.

Chris Lattner 944200be45 If a function is vararg, never pass inreg arguments in registers. Thanks to 
Anton for half of this patch.

Evan Cheng cea02ffd05 Look for VECTOR_SHUFFLE that's identity operation on either LHS or RHS. This can happen before DAGCombiner catches it.

Dan Gohman c98815ba32 Define the pushq instruction for x86-64. 
llvm-svn: 37625
 2007-06-18 14:12:56 +00:00
Bill Wendling 094a4e813a Revert patch. It regresses: 
define double @test2(i64 %A) {
   %B = bitcast i64 %A to double
   ret double %B
}

$ llvm-as < t.ll | llc -march=x86-64

before:

         .align  4
         .globl  _test2
_test2:
         movd %rdi, %xmm0
         ret

after:

_test2:
         subq $8, %rsp
         movq %rdi, (%rsp)
         movsd (%rsp), %xmm0
         addq $8, %rsp
         ret

Evan Cheng 842be09d86 Stupid cut-n-paste bug caused me soooo much grief. Why wasn't there a compilation warning? I blame it on the FE folks. 
llvm-svn: 37484

Bruno Cardoso Lopes 35e43c49b0 Initial Mips support, here we go! =) 
- Modifications from the last patch included
  (issues pointed by Evan Cheng are now fixed).
- Added more MipsI instructions.
- Added more patterns to match branch instructions.

 2007-06-04 18:54:57 +00:00
Chris Lattner 446548d2a3 update this entry, now that Anton implemented shift/and lowering for 
switches.  There is one really easy isel thing here with tst we are not
getting.

Chris Lattner 3e3ff30aa2 Fix the asmprinter so that a globalvalue can specify an explicit alignment 
smaller than the preferred alignment, but so that the target can actually
specify a minimum alignment if needed.  This fixes some objc protocol
failures Devang tracked down.

llvm-svn: 37373
 2007-05-31 18:57:45 +00:00
Evan Cheng 19eeee41ca For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias. 
llvm-svn: 37351
 2007-05-29 23:34:19 +00:00
Evan Cheng a6e9a4ce07 For ldrb, strh, etc., the condition code is before the width specifier. e.g. streqh, not strheq.

Dale Johannesen f9cbdc676c name change requested by review of previous patch 
llvm-svn: 37289
 2007-05-22 18:31:04 +00:00
Dale Johannesen 82810c8a13 Make tail merging the default, except on powerPC. There was no prior art 
for a target-dependent default with a command-line override; this way
should be generally usable.
